Project-GC doesn't have access to unpublished caches, hence the "?" you see there. Once your challenge cache is published (or within a reasonable time thereafter), your cache name will appear there.
PS: your proposed challenge violates rule 9 of the guidelines:
Time-Limited: Not Acceptable: Requiring more than one find on any day or calendar date, even if cumulative. Example, find 5 caches for every date of the Finds for Each Day of the Year grid.
